HEX Here3+ UAV High-Precision Differential GPS Navigation

The Here 3+ GPS is a cost-effective navigation unit with a high precision GNSS chip and real-time dynamic differential technology (with base station required) to achieve centimeter-level accuracy under ideal conditions. The new design has a wider range of LED lights and better dust and splash protection. (Note: Due to the complexity of the drone environment, we do not guarantee that it will be waterproof in all cases.) And the use of DRONECAN standard communication protocol has high data transmission, strong expansion, strong anti-interference, high real-time performance. Her3+ with DroneCAN FD can reach bus speed of 8Mbit. The Here3 uses the STM32F302 processor, while the Here3+ is upgraded to a dual-core STM32H757 processor with a speed of 400MHz, 2MByte Flash and 1MByte RAM. Firmware updates are supported and available directly from the Mission Planner ground station. Built-in a complete set of navigation units (electronic compass, gyroscope, accelerometer) to meet more navigation needs.
